Enum Constant Summary

Enum Constants

Enum Constant and Description
DEFAULT_CONSTRUCTOR This strategy is adding a default constructor that calls it's super types default constructor.
IMITATE_SUPER_TYPE This strategy is adding all constructors of the instrumented type's super type where each constructor is directly invoking its signature-equivalent super type constructor.
IMITATE_SUPER_TYPE_PUBLIC This strategy is adding all constructors of the instrumented type's super type where each constructor is directly invoking its signature-equivalent super type constructor.
NO_CONSTRUCTORS This strategy is adding no constructors such that the instrumented type will by default not have any.

Method Summary

Modifier and Type	Method and Description
MethodRegistry	inject(MethodRegistry methodRegistry, MethodAttributeAppender.Factory defaultMethodAttributeAppenderFactory) Returns a method registry that is capable of creating byte code for the constructors that were provided by the ConstructorStrategy.extractConstructors(net.bytebuddy.instrumentation.type.TypeDescription) method of this instance.
static ConstructorStrategy.Default	valueOf(String name) Returns the enum constant of this type with the specified name.
static ConstructorStrategy.Default[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

NO_CONSTRUCTORS

public static final ConstructorStrategy.Default NO_CONSTRUCTORS

This strategy is adding no constructors such that the instrumented type will by default not have any. This is legal by Java byte code requirements. However, if no constructor is added manually if this strategy is applied, the type is not constructable without using JVM non-public functionality.

DEFAULT_CONSTRUCTOR

public static final ConstructorStrategy.Default DEFAULT_CONSTRUCTOR

This strategy is adding a default constructor that calls it's super types default constructor. If no such constructor is defined, an IllegalArgumentException is thrown. Note that the default constructor needs to be visible to its sub type for this strategy to work.

IMITATE_SUPER_TYPE

public static final ConstructorStrategy.Default IMITATE_SUPER_TYPE

This strategy is adding all constructors of the instrumented type's super type where each constructor is directly invoking its signature-equivalent super type constructor. Only constructors that are visible to the instrumented type are added, i.e. package-private constructors are only added if the super type is defined in the same package as the instrumented type and private constructors are always skipped.

IMITATE_SUPER_TYPE_PUBLIC

public static final ConstructorStrategy.Default IMITATE_SUPER_TYPE_PUBLIC

This strategy is adding all constructors of the instrumented type's super type where each constructor is directly invoking its signature-equivalent super type constructor. Only public constructors are added.

Method Detail

values

public static ConstructorStrategy.Default[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ConstructorStrategy.Default c : ConstructorStrategy.Default.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ConstructorStrategy.Default valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

inject

public MethodRegistry inject(MethodRegistry methodRegistry,
                             MethodAttributeAppender.Factory defaultMethodAttributeAppenderFactory)

Description copied from interface: ConstructorStrategy

Returns a method registry that is capable of creating byte code for the constructors that were provided by the ConstructorStrategy.extractConstructors(net.bytebuddy.instrumentation.type.TypeDescription) method of this instance.

Specified by:

inject in interface ConstructorStrategy

Parameters:

methodRegistry - The original method registry.

defaultMethodAttributeAppenderFactory - The default method attribute appender factory.

Returns:

A method registry that is capable of providing byte code for the constructors that were added by this strategy.
